采用硅烷偶联剂KH-570对纳米SiO_2进行了表面接枝改性,并探讨了改性材料对阿维菌素的吸附性能.通过X射线衍射(XRD)、扫描电子显微镜(SEM)、傅立叶变换红外光谱(FTIR)等技术对表面改性纳米SiO_2的结构和性能进行了分析.结果表明,纳米SiO_2粒子经KH-570进行表面改性后,其分散性得以改善,对阿维菌素的包封率比改性前的大幅提高,提高率最高达92.6%.用KH-570改性的纳米SiO_2可作为一种较为理想的新型生物农药栽体.

SiO_2 nanoparticles were modified by silane coupling agent KH-570 and their effects on the adsorption capacity of abamectin were studied. The structure and physicochemical properties of silane modified SiO_2 were characterized by XRD, SEM and FTIR. It was shown that SiO_2 nanoparticles were modified by KH-570 successfully and dispersivity of the surface modified SiO_2 nanoparticles was improved. As a result, SiO_2 nanoparticles modified by KH-570 can be used as an ideal carrier for biological pesticides.
